RECKLESS CYCLISTS do share culpability for traffic incidents, and advocates should accept this. Yet Derrick Z. Jackson’s recent article (“To get respect, cyclists need to show some, too,” June 23) omits an important point: Re-envisioned streets and stoplights do not simply add bonuses for cyclists, but address fundamental and dangerous inadequacies. As a cyclist, I frequently preempt traffic lights because to await the flow of traffic would put me at great risk of collision with turning vehicles. Multimodal transit requires restructuring how we travel and which social and environmental cues lead to split-second decisions.
